Irrigated agriculture and the use of water resources in agriculture face the challenges of sustainable development. Research has advanced our knowledge of water use by crops, soil-water-solutes interactions, and the engineering and managerial tools needed to mobilize, convey, distribute, control and apply water for agricultural production. However, the achievements booked in user practice have revealed the need for new developments in the areas of resource conservation, control of environmental and health impacts, modernisation of technologies and management, economic viability and the social acceptance of changes. The contributions to Sustainability of Irrigated Agriculture cover most of the relevant disciplines. Besides its multidisciplinarity, the different origins, experience, backgrounds and practices of the authors provide a wide, in-depth analysis of the various aspects of water resource utilization in agriculture. The papers review scientific, technical and managerial aspects, highlighting the main problems, issues and future developments. The book covers the different aspects of sustainability, including environmental, technical, economic, institutional and social ones. Advances in irrigation science and engineering are dealt with, both on- and off-farm. Special attention is paid to the different components of water quality management, to the transfer of technology, and to capacity building.

This volume presents a selection of the main contributions made to the international conference on Integrated Water Resources Management (IWRM) entitled ‘Management of Water in a Changing World: Lessons Learnt and Innovative Perspectives’ that was held from 12 to 13 October 2011 in Dresden, Germany. The book summarise the main messages issuing from the conference and contains selected papers which were presented during the conference, either as keynote lectures in plenary sessions or as submitted papers in one of the thematic sessions. The key themes of the book are: Water resources in changing environments Groundwater management Technologies and implementation Water management indicators at different scales Information and decision support systems Water governance: actors and institutions The book provides an overview on important issues concerning the conceptual framework of integrated water resources management (IWRM). All presentations and abstracts and the corresponding PowerPoint presentations as well as a video recording of the panel discussion are available at the conference website http://www.bmbf.iwrm2011.de. Readers are encouraged to complete their review of the conference and its messages by consulting this interesting on-line source of accompanying scientific material.

This study examines ways to increase food security, reduce poverty and achieve economic growth in sub-Saharan Africa with ‘water’ through increased participation of the private sector and publicprivatepartnerships. This report is a summary of the findings from a review of the literature and critical analysis thereof. The ‘private sector’ includes all farmers, farm households, and agriculture-based micro, small and medium enterprises (MSMEs). That is: all entities involved in crop, livestock and fish production and marketing, in post-harvest activities and food processing, and in supply chains for the goods, services and information used in the process. The study examines different types of agricultural water development and management. These include smallholder subsistence farming, cultivation of profit-oriented high-value crops, and peri-urban agriculture, as well as successful examples of private sector involvement in various functions or processes, including planning, design, construction, operations and maintenance. The spotlight on ‘water’ does not imply that other factors, such as off farm employment, market development and education, are unimportant.
